Interaction of multiply charged ions with isolated polycyclic aromatic hydrocarbon molecules

The interaction of multiply charged ions (He2+, O3+, and Xe20+, v ≤ 0.6 a.u.) with gas phase pericondensed polycyclic aromatic hydrocarbon (PAH) molecules (pyrene and coronene) was studied. Positively charged ionic products were analyzed with a linear time-of-flight mass spectrometer.
